erratum: answers a weaker question

| Jun 25, 2020 at 12:31 | comment | added | Hans | I have added a counterexample where $\Phi$ is not linear. | |
| Jun 25, 2020 at 8:47 | comment | added | Aurel | Oh, I missed that requirement! I'll have to check whether it is. | |
| Jun 25, 2020 at 7:05 | comment | added | Hans | Thanks for the answer. Could you also explain why $\Phi$ is a linear map? | |
